Newton's Laws of Motion

The overall force on an object when all the individual forces acting on it are added together

• Momentum
• Net force
• Velocity
• Unbalanced force

what is weight measured in?

• newton meters

• grams

• newtons

• kilograms

A push or pull exerted on an object

• Force
• Net force
• Momentum
• Speed

What is the force that pulls us towards the Earth?

• gravity
• weight
• friction
• mass

When an object is moving, friction acts in the _______ direction as the motion.

• perpendicular

• same

• opposite

• precise

which is the correct formula for weight?

• weight x mass = gravitational field strength

• mass ÷ gravitational field strength = weight

• mass x gravitational field strength = weight

A person would weigh less on on the Moon than on the Earth because . . .

• Moon has more mass, and therefore more gravity
• Moon has less mass, and therefore more gravity
• Moon has more mass, and therefore less gravity
• Moon has less mass and therefore less gravity

What is the net force?

• 400 N Up
• 400 N Down
• - 400 N Down
• 800 N Down

A type of friction that occurs when air pushes against a moving object it to decelerate.

• surface area

• air resistance

• velocity

• gravity

Which force produces a change in motion?

• unbalanced force
• balanced force
• gravitational force
• frictional force
