Physics Motion Review

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time. It can be caused by a change in speed or direction.

Front

What is velocity?

Back

Velocity is a vector quantity that refers to the rate at which an object changes its position. It has both magnitude and direction.

Front

What does it mean for an object to be in motion?

Back

An object is in motion if its position changes relative to a reference point over time.

Front

What is centripetal acceleration?

Back

Centripetal acceleration is the acceleration directed towards the center of a circular path, experienced by an object moving in a circle.

Front

How does direction affect velocity?

Back

Since velocity is a vector, any change in direction results in a change in velocity, even if the speed remains constant.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity includes both speed and direction.

Front

What is a vector?

Back

A vector is a quantity that has both magnitude and direction, such as force, velocity, and acceleration.

Front

What is a scalar?

Back

A scalar is a quantity that has only magnitude and no direction, such as mass, temperature, and speed.

Front

What does it mean for an object to be at rest?

Back

An object is at rest if its position does not change with respect to a reference point over time.

Front

What is the formula for acceleration?

Back

Acceleration (a) is calculated using the formula: a = (final velocity - initial velocity) / time.
