Physics-Semester 1 Review

Front

What is the net force when two equal forces act on the same object in opposite directions?

Back

Zero.

Front

What is the force of gravity on a person or object at the surface of a planet called?

Back

Weight.

Front

What are the units for measuring Velocity?

Back

m/s.

Front

What is the velocity of a ball at the top of its path when thrown straight up?

Back

0 m/s.

Front

How far does a car go that starts from rest and accelerates at 31 m/s² for 10 seconds?

Back

1550 m.

Front

Define Force in physics.

Back

A push or pull on an object resulting from its interaction with another object.

Front

What is the formula for calculating Weight?

Back

Weight = Mass × Gravity (W = m × g).

Front

What is Inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the difference between Mass and Weight?

Back

Mass is the amount of matter in an object, while Weight is the force exerted by gravity on that mass.

Front

What is the formula for calculating Velocity?

Back

Velocity = Displacement / Time.
