What else can I help you with?
How much force is needed to accelerate your body at a rate of 2 ms2 if you weigh 45kg?
Force = mass x acceleration. I'll let you do the math.
What is the measure of a body's resistance to acceleration?
Mass measures the body's resistance to acceleration.
Can an object accelarate without friction?
Yes, an object can accelerate without friction. The only thing that is needed to accelerate an object is net force acting on it should not be zero. Then the accleration of body is given by Newton's 2nd Law: F = m*a . For example Rockets in space experience no friction, but they accelerate due to force on them by the exhaust gases.
When a body is falling freely which force act on it?
When a body is falling freely, the only force acting on it is gravity. This force causes the body to accelerate downwards at a rate of 9.81 m/s^2 near the surface of the Earth.
When you begin to walk forward what exerts the force allowing you to accelerate?
When you begin to walk forward, the force exerted by your leg muscles on the ground generates a reaction force that propels you forward. This force pushes against the ground, causing your body to accelerate in the direction you are walking.
How much force is needed to accelerate your body at a rate of 2 ms2 if you weigh 45 kg?
90 N

When can an object have Acceleration?
Whenever there is a resultant force acting on a body which is having some mass, then that body will accelerate (or) A body whose velocity is changing with respect to time and having some mass then the body will accelerate.
How much force is needed to accelerate your body at a rate of 2 m per s per s if you weigh 45 kg?
F = ma. F = 45 x 2 = 90 N.
Is an unbalanced force needed to start motion?
Yes, in order for an object to accelerate or decelerate, the resultant force cannot be zero.To cause a car to accelerate, the forward force (thrust force/engine force) must be greater than the backwards force (friction force/brake force). When this unbalanced force is achieved, the body will initiate its motion.
When a force is applied to a body in what direction will the body accelerate?
Acceleration is in the same direction as the applied force.
What is the measure of a body's resistance to acceleration?
Mass measures the body's resistance to acceleration.
How does the unbalanced force affect the motion of the body?
A unbalanced force causes a body to accelerate. (From Newton's second law)
What is the force that opposes?
Friction.Called inertia. To accelerate a body the force is mass times acceleration. No force = no acceleration. People say " the force is opposed by the massacceleration"
