Amplify - Force and Motion 3.1 and 3.2

Front

What is velocity?

Back

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

Front

What happens to the velocity of an object when it experiences a collision?

Back

The velocity of an object can change, which may include stopping, speeding up, or changing direction.

Front

What is the relationship between force and motion?

Back

Force is a push or pull that can cause an object to accelerate, change direction, or change shape.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object over time.

Front

What is the definition of collision?

Back

A collision is the moment when two objects hit each other.

Front

What is the effect of mass on acceleration?

Back

The greater the mass of an object, the less it will accelerate in response to a given force.

Front

What direction must a force be applied to increase the speed of an object?

Back

The force must be applied in the same direction as the object's velocity.

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.
