Newman's Energy/Force Review

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it comes into contact with another surface.

Front

How do rubber rain boots affect friction?

Back

Rubber rain boots increase the amount of friction between the feet and the ground, providing better grip.

Front

What happens to a bike's motion when pedaling stops?

Back

The bike slows down gradually due to friction between the ground and tires.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state, such as a ball held in someone's hands.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, such as a ball sailing through the air.

Front

What is the effect of surface texture on force required to move an object?

Back

A rough surface, like sandpaper, requires a greater force to pull an object compared to a smooth surface.

Front

What determines the speed of two objects with the same mass when pushed?

Back

The amount of force applied determines the speed of two objects with the same mass when pushed.

Front

What is gravity?

Back

Gravity is a force that pulls objects toward each other, such as the Earth pulling objects toward its center.

Front

What is the relationship between mass and force?

Back

The greater the mass of an object, the more force is required to move it.

Front

What is an example of an object with potential energy?

Back

A ball held in someone's hands is an example of an object with potential energy.
