Year 10 - Physics

If you are driving forward and suddenly break, what would happen to your body and which law does that demonstrate?

• go back, 1st Law
• move forward, 1st Law

Forces always act in equal and opposite pairs.

• Newton's 1st Law
• Newton's 3rd Law

What force slows objects down and keeps them from moving?

• Friction
• Acceleration

An object in motion will stay in motion and an object at rest will stay at rest unless acted upon by an outside force.  Which law does this describe?

• Newton's 1st Law
• Newton's 2nd Law

If there is a big mass, it would need a stronger force to accelerate it.  Which law does this describe?

• Newton's 1st Law
• Newton's 2nd Law
• Newton's 3rd Law

What is the force applied to all objects on Earth?

• Earthquakes
• Gravity

A student leaves a pencil on a desk and it stays there until I pick it up. 

• 1st Law
• 2nd Law

A picture is hanging on the wall, and is not moving. 

• 1st Law
• 3rd Law 

What is velocity?

• the quickness of an object
• the location of an object
• acceleration
• speed in a specific direction

What is the formula to calculate speed?

• S = t/d
• S = d/t
• S = d x t
• S = t x d
