What else can I help you with?
Acceleration is the change in distance over time True or false?
False. Acceleration is a change of speed or direction over time.
Acceleration will only speed up an object True or false?
False. At least the way "acceleration" is described in physics, acceleration involves any change in velocity - so the "accelerating" object can speed up, slow down, or simply change direction.
Both speed and acceleration include the direction of an objects motion true or false?
This is not true. Acceleration includes direction, but speed does not. Speed in a particular direction is called velocity.
Is it true or false Acceleration is the magnitude of average velocity?
False. Acceleration is the rate of change of velocity. Average velocity is the total displacement divided by the total time.
Is it true or false that For a particle in uniform circular motion the instantaneous-acceleration vector is directed radially outward?
True. In uniform circular motion, the particle's velocity is tangential to the circular path, and the acceleration is directed radially inward, towards the center of the circular path. This centripetal acceleration causes the change in direction of the particle's velocity, but the magnitude of the velocity remains constant.

This centripetal acceleration causes the change in direction of the particle's velocity, but the magnitude of the velocity remains constant.
When you change direction are you accelerating true or false?
True. Acceleration is any change in velocity, including a change in direction. So when you change direction, you are indeed accelerating.
Is it true or false that For a particle undergoing uniform circular motion the instantaneous-acceleration vector equals zero.?
False. In uniform circular motion, the instantaneous acceleration is directed towards the center of the circle, which is called the centripetal acceleration. This acceleration is responsible for changing the direction of the velocity of the particle, even though its speed remains constant.
Is it true or false balanced force cause a change in motion?
though different terminology is used. Motion is thought of in acceleration and velocity. Now, velocity is just the distance covered over an amount of time, or speed. Acceleration is the change in speed. In general terms, any object that is standing still is being acted upon by equal and opposite forces, and if one of those forces was changed, then the object would undergo acceleration. Think of a person holding a coffee cup. Gravity is working on the object to pull it down, and his or her arm is pulling equally in the opposite direction to keep it up. If the person were to let go, there wouldn't be the upward force, and the cup would accelerate towards the Earth, and its "motion" would be changed. TRUE!
Is Acceleration is the magnitude of average velocity true or false?
False
Does Motion occurs when there is a change in speed true or false?
True. Motion occurs when an object changes its position relative to a reference point. A change in speed indicates a change in the rate of motion, which can result in the object moving at a different pace or direction.
Is it true or false that balanced forces can change an object's direction?
False. Balanced forces do not change an object's direction. Balanced forces only keep an object at rest or in a uniform motion in a straight line. If an object changes direction, unbalanced forces are acting on it.
True or false if you know an objects mass and acceleration you can determine the net force being exerted on the object?
False. You will know nothing at all about any force acting perpendicular to the direction of motion.
