Amplify Force and Motion, Chapters 1 and 2

Front

What is required to cause an object to change its velocity?

Back

A force is required to cause an object to change its velocity.

Front

What is the force applied to an object as it moves across a surface called?

Back

The force applied to an object as it moves across a surface is called friction.

Front

In which direction must a force be applied to cause an object to slow down?

Back

A force must be applied in the opposite direction of velocity to cause an object to slow down.

Front

What does the change in velocity of an object depend on?

Back

The change in velocity of an object depends on the direction of the force exerted on that object.

Front

What is velocity?

Back

Velocity is the speed of an object in a particular direction.

Front

What is the relationship between force and motion?

Back

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

Front

What happens to an object's motion when a net force acts on it?

Back

When a net force acts on an object, it causes the object to accelerate in the direction of the net force.

Front

What is friction and how does it affect motion?

Back

Friction is a force that opposes motion between two surfaces in contact, slowing down or stopping the movement.

Front

What is the difference between speed and velocity?

Back

Speed is how fast an object is moving, while velocity includes both speed and direction.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.
