Unit 3: Force, Speed, & Newton (Final Bank)

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken. It is measured in meters per second (m/s) or kilometers per hour (km/h).

Front

How do you calculate average speed?

Back

Average speed = Total distance / Total time.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = m * a).

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object and does not change regardless of location. Weight is the force exerted by gravity on that mass and can change depending on the gravitational field.

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 with the same speed and in the same direction unless acted upon by a net external force.

Front

What is constant velocity?

Back

Constant velocity means an object is moving at a fixed speed in a straight line without changing direction.

Front

What is net force?

Back

Net force is the total force acting on an object after all the forces are combined. It determines the object's acceleration.

Front

What happens to the net force when an object is in free fall at constant velocity?

Back

The net force is 0 N because the force of gravity is balanced by the air resistance.

Front

How do you find velocity from distance and time?

Back

Velocity = Distance / Time.

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force is the Newton (N).
