Force and Motion Test Review

Front

What is a reference point?

Back

A reference point is a stationary object used to determine the position of another object.

Front

What does speed measure?

Back

Speed measures how fast an object is moving, calculated as distance traveled over time.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time

Front

What does a horizontal line on a distance-time graph indicate?

Back

A horizontal line indicates that the object is not moving.

Front

What is a balanced force?

Back

A balanced force occurs when two forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, which can occur due to a change in speed or direction.

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 is a vector quantity that includes both speed and direction.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the effect of gravity on objects in motion?

Back

Gravity pulls objects toward the center of the Earth, affecting their speed and direction of motion.

Front

What is the relationship between force and motion?

Back

Force is any interaction that, when unopposed, will change the motion of an object.
