5.6D Force and Motion

Front

What is friction?

Back

Friction is a force that opposes the motion of an object. It occurs when two surfaces rub against each other.

Front

What is gravity?

Back

Gravity is a force that pulls objects toward the center of the Earth. It is what keeps us grounded and causes objects to fall.

Front

What is motion?

Back

Motion is the change in position of an object over time. It can be described in terms of speed, direction, and distance.

Front

What is an example of gravitational force?

Back

An example of gravitational force is dropping a pencil on the ground; it falls due to the pull of gravity.

Front

What force pulls objects toward the Earth?

Back

The force that pulls objects toward the Earth is called gravity.

Front

What is the role of friction in motion?

Back

Friction slows down or stops the motion of an object. It can make it harder to move objects.

Front

What happens to an object in motion if no forces act on it?

Back

If no forces act on an object in motion, it will continue to move in a straight line at a constant speed.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.

Front

What is an example of a force?

Back

An example of a force is pushing a grocery cart; it involves applying a force to move the cart.

Front

What is the effect of air pressure on falling objects?

Back

Air pressure can slow down the fall of objects due to air resistance, which is a type of friction.
