Forces and Motion Lesson 1 & 2 Review

Front

What does a motion graph that is flat represent?

Back

A body at rest.

Front

What is the net force on an object when two equal forces act in opposite directions?

Back

The net force is zero, meaning there is no change in motion.

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 a balanced force?

Back

Equal forces acting on an object that do not cause a change in its motion.

Front

What happens to an object when it experiences acceleration?

Back

The object either speeds up, slows down, or changes direction.

Front

Define acceleration.

Back

Acceleration is the rate of change of velocity of an object.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

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 unbalanced forces on an object?

Back

Unbalanced forces cause an object to accelerate in the direction of the net force.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).
