Unit 2 Forces and Motion Assessment

Front

What is the force that causes an object to move in a specific direction?

Back

Applied force is the force that causes an object to move in a specific direction.

Front

How does mass influence kinetic energy?

Back

Kinetic energy increases with an increase in mass.

Front

What is the force acting downward on an object due to gravity?

Back

Gravity is the force acting downward on an object.

Front

Calculate the average speed if a man and a ball travel 63 m in 9 seconds.

Back

Average speed = Distance / Time = 63 m / 9 s = 7 m/s.

Front

Why does a person move forward when pushing backward with a paddle?

Back

The water pushes back with an equal and opposite force.

Front

What is the definition of force?

Back

Force is a push or pull on an object that can cause it to change its motion.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What is friction?

Back

Friction is the force that opposes the motion of an object.

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object's mass (Weight = mass × gravity).

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.
