Forces

Front

What is a force?

Back

A force is a push or pull that can change the motion of an object.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, often caused by the contact between surfaces.

Front

How does friction affect motion?

Back

Friction slows down or stops the motion of objects.

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 displacement?

Back

Displacement is the shortest distance from the initial to the final position of an object, including direction.

Front

What is work in physics?

Back

Work is done when a force causes an object to move in the direction of the force.

Front

What is the relationship between mass and force?

Back

The greater the mass of an object, the more force is needed to change its motion.

Front

What is an inclined plane?

Back

An inclined plane is a flat surface that is tilted at an angle, used to help lift objects.

Front

How does the height of a ramp affect the distance a toy car rolls?

Back

Increasing the height of a ramp generally increases the distance a toy car rolls due to greater potential energy.

Front

What is the effect of surface type on motion?

Back

Different surface types can change the amount of friction, affecting how far an object rolls.
