How long does it take an object in motion to stop What is a formula to help determine when an object in motion will stop and what variables need to be known?
(first calculate deceleration rate:)
if you know the braking force and mass, you can calculate deceleration.
d=f/m ((m/s)/s)
say mass = 100 kg, force = 1000 n, then d = -10 (m/s)/s (negative because you're slowing down)
(now calculate distance and time during deceleration:)
say initial velocity (u) = 100 m/s
say final velocity (v) = 0 m/s
deceleration (d) = -10 (m/s)/s
time taken to stop under braking (t) = v-u/d = 0 -100/-10 = 10 seconds
distance taken to stop under braking (s) = (u*t )+( a*t^2)/2 = 1500 metres

What is called the energy due to object's motion?
Kinetic energy is the energy associated with an object's motion. It depends on the object's mass and velocity, with the formula given by KE = 0.5 * mass * velocity^2.
What does mv squared mean?
"mv²" refers to the kinetic energy formula, where "m" is the mass of an object in motion and "v" is the velocity of the object. The formula calculates the energy that an object possesses due to its motion.
When you multiply half the mass of an object by its speed squared you calculate its?
You are calculating the kinetic energy of the object using the formula KE = 0.5 * m * v^2, where m is the mass and v is the speed of the object. This formula gives you the energy associated with the object's motion.
What can kinetic energy be described as?
The energy a body has because of it motion.
What is the formula of newton first law of motion?
Newton's first law of motion states that an object will remain at rest or in uniform motion unless acted upon by an external force. Mathematically, it can be expressed as ΣF = 0, where ΣF represents the net force acting on an object and 0 indicates that the object's velocity remains constant.
How can one determine the g force experienced by an object in motion?
To determine the g force experienced by an object in motion, you can use the formula: g force acceleration due to gravity x mass of the object. This formula helps calculate the force exerted on an object as it accelerates or decelerates.
How can one determine the centripetal velocity of an object in motion?
To determine the centripetal velocity of an object in motion, you can use the formula: v r, where v is the centripetal velocity, r is the radius of the circular path, and is the angular velocity of the object. This formula relates the speed of the object to the radius of the circular path and how quickly the object is rotating around that path.
How can one determine the tangential acceleration of an object in motion?
To determine the tangential acceleration of an object in motion, you can use the formula: tangential acceleration radius x angular acceleration. The tangential acceleration represents the rate at which the object's speed is changing along its circular path.
How do you calculate the g force experienced by an object in motion?
To calculate the g-force experienced by an object in motion, you can use the formula: g-force acceleration due to gravity (9.81 m/s2) x the object's acceleration in m/s2. This formula helps determine the force exerted on an object relative to gravity while it is in motion.
Is needed to determine whether an object is in motion?
A Reference Point A reference point is needed to determine if an object is in motion.
How to find the vertical velocity of an object in motion?
To find the vertical velocity of an object in motion, you can use the formula: vertical velocity initial vertical velocity (acceleration due to gravity x time). This formula takes into account the object's starting vertical velocity, the acceleration due to gravity (usually -9.8 m/s2), and the time the object has been in motion. By plugging in the values for these variables, you can calculate the vertical velocity of the object.
What is the net velocity formula and how is it used to calculate the overall motion of an object?
The net velocity formula is the total velocity of an object, taking into account both its speed and direction. It is calculated by adding up all the individual velocities of the object. This formula helps determine the overall motion of an object by considering how its speed and direction change over time.
How to find the kinetic energy of an object?
To find the kinetic energy of an object, you can use the formula: KE 0.5 mass velocity2. This formula calculates the energy that an object possesses due to its motion. Simply plug in the mass of the object and its velocity into the formula to determine its kinetic energy.
How can one determine the friction force when given the mass and acceleration of an object?
To determine the friction force when given the mass and acceleration of an object, you can use the formula: friction force mass x acceleration. This formula helps calculate the force resisting the motion of the object due to friction.
What is a place or object used in comparison to determine if an object is in motion is a?
A reference point is a place or object used in comparison to determine if an object is in motion. It serves as a frame of reference to establish the motion of an object relative to a fixed point.
How can one determine the vertical velocity of an object?
To determine the vertical velocity of an object, you can use the formula: vertical velocity initial vertical velocity (acceleration due to gravity x time). This formula takes into account the object's initial velocity and how gravity affects its motion over time.
How do you calculate the friction force when given the mass and acceleration of an object?
To calculate the friction force on an object, you can use the formula: Friction force mass x acceleration. This formula helps determine the force resisting the object's motion due to friction.
