Newman's Physics Review

Front

What happens to the velocity of a ball in a head-on collision with another ball of equal mass?

Back

The first ball will move forward at a slower rate.

Front

What is the effect of a large force applied to an object?

Back

It causes a significant change in its speed and/or direction.

Front

What is gravity?

Back

Gravity is a force that exists between all objects with mass, pulling them towards each other.

Front

What happens to a baseball when it is hit?

Back

A baseball falls to the ground after being hit.

Front

How does gravity affect planets?

Back

Gravity keeps the planets orbiting the Sun.

Front

What is the relationship between mass and gravity?

Back

Objects with more mass exert a stronger gravitational pull.

Front

What is inertia?

Back

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

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity.
