What is Newton's 3rd Law of Motion?

Back

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

Front

What is the final velocity of an object thrown upwards and caught at the same height, neglecting air resistance?

Back

0 m/s

Front

In which direction is there zero acceleration for a projectile?

Back

There is no direction with zero acceleration; acceleration is always present due to gravity.

Front

How do you calculate acceleration using net force and mass?

Back

Acceleration (a) = Net Force (F) / Mass (m).

Front

What happens to the velocity of an object in free fall?

Back

It increases, moving faster and faster due to gravity.

Front

What is Newton's 1st 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 the formula for calculating the net force acting on an object?

Back

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

Front

What is the acceleration of an object with a net force of 10 N and a mass of 4 kg?

Back

2.5 m/s².

Front

What is the effect of air resistance on falling objects?

Back

Air resistance opposes the motion, reducing acceleration and terminal velocity.

Front

What is the significance of the angle of launch for projectiles?

Back

The angle affects the range and height of the projectile.
