Forces and Motion/Forces Cause Change Practice

Front

What is friction?

Back

Friction is a force that opposes the motion of an object. It acts in the opposite direction to the movement.

Front

What is gravity?

Back

Gravity is a force that pulls objects toward each other, such as the pull of the Earth on objects, causing them to fall.

Front

What happens to an object's motion when a force is applied?

Back

When a force is applied to an object, it can cause the object to start moving, stop moving, or change direction.

Front

How does mass affect motion?

Back

The greater the mass of an object, the more force is needed to change its motion. Reducing mass can make an object move faster with the same force.

Front

What is a push force?

Back

A push force is a force that moves an object away from the person or thing applying the force.

Front

What is a pull force?

Back

A pull force is a force that moves an object closer to the person or thing applying the force.

Front

What is the relationship between force and motion?

Back

Force causes changes in motion. If no force acts on an object, it will remain at rest or continue moving at a constant speed.

Front

What is an example of a force acting in the opposite direction?

Back

Friction acts in the opposite direction to the motion of an object, slowing it down.

Front

What is the effect of removing weight from an object being pushed?

Back

Removing weight decreases the mass of the object, allowing it to move faster with the same amount of force.

Front

What is an example of a push and pull in sports?

Back

In volleyball, a player pushes the ball over the net, and gravity pulls it back down to the ground.
