Front

What is a projectile?

Back

A projectile is something moving in two dimensions with influence from only gravity.

Front

What is the horizontal acceleration of a projectile (neglecting air resistance)?

Back

0 m/s².

Front

How much energy is stored in a spring with a spring constant of 4 N/m compressed by 0.25 m?

Back

0.125 J.

Front

Which option depicts the velocity of a blowing ball?

Back

C.

Front

What is the NET FORCE if the forces are 17 N to the right and 7 N to the left?

Back

17 N to the right.

Front

Define 'net force'.

Back

Net force is the vector sum of all the forces acting on an object.

Front

What is the formula for calculating the potential energy stored in a spring?

Back

Potential Energy = 1/2 k x², where k is the spring constant and x is the compression.

Front

What does it mean for an object to be in free fall?

Back

An object in free fall is only influenced by gravity, with no other forces acting on it.

Front

Explain the concept of horizontal motion in projectile motion.

Back

In projectile motion, horizontal motion is uniform, meaning the horizontal velocity remains constant.

Front

What is the acceleration due to gravity on Earth?

Back

Approximately -9.8 m/s².
