Unit 2 Force & Motion Review

Front

What is the relationship between mass and kinetic energy (KE)?

Back

As mass increases, the kinetic energy (KE) increases.

Front

What is the equation that describes the relationship between force, mass, and acceleration?

Back

F = ma

Front

What determines the kinetic energy of an object?

Back

Kinetic energy depends on both the mass of the object and its velocity.

Front

True or False: A car moving at a constant speed is accelerating.

Back

False

Front

What does a graph showing a straight horizontal line indicate about an object's motion?

Back

The object is moving at a constant speed.

Front

If two objects are moving at the same speed, how does their mass affect their kinetic energy?

Back

The object with more mass has more kinetic energy.

Front

What is the formula for calculating kinetic energy?

Back

KE = 1/2 mv², where m is mass and v is velocity.

Front

What does the term 'force' mean in physics?

Back

Force is a push or pull on an object that can cause it to accelerate.

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force is the Newton (N).

Front

What is acceleration?

Back

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