Front

What force causes all objects to slow down and then eventually stop?

Back

Friction is the force that opposes the motion of an object, causing it to slow down and eventually stop.

Front

A stronger force can cause a ______ change in velocity.

Back

greater - A stronger force results in a greater change in velocity.

Which toy boat(s) experienced the strongest force when it was bumped?

Back

All three toy boats experienced the same strength force because they changed speed by the same amount.

Front

Speed in a particular direction is ..... ?

Back

Velocity - Velocity is defined as speed in a specific direction.

Front

For every action there is an equal and opposite reaction.

Front

What is the definition of friction?

Back

Friction is a force that resists the sliding or rolling of one surface over another.

Front

What is the relationship between force and acceleration?

Back

According to Newton's 2nd Law, force equals mass times acceleration (F=ma). A greater force results in greater acceleration.

Front

What is inertia?

Back

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

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What does Newton's 1st Law state?

Back

Newton's 1st Law states that an object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by a net external force.
