2A/D Forces AfL Part 1

What is the formula for calculating weight?

How does an increase in height affect the weight of an object?

• Weight increases with height.

• Weight decreases with height.

• Height does not affect weight.

• Weight is inversely proportional to height.

Which of the following statements is true about the effect of gravitational field strength on weight?

• Weight is independent of gravitational field strength.

• Weight decreases as gravitational field strength increases.

• Weight increases as gravitational field strength increases.

• Weight decreases as gravitational field strength.

What are the units for Weight?

• Kg

• N

• N/kg

• Joules

What force causes objects falling near Earth's surface to slow down?

• Gravity
• Air Resistance
• Centripetal Force
• Newtons

In a football game, footballers 'head' the ball to change the direction of the ball.

What is the motion of the object?

• Change the direction of a moving object

• Make a moving object stop

• Make a moving object move faster

• Make a stationary object move

What is the effect of force shown here?

• change in shape

• change in direction

• change in speed

• force can stop an object

10. A ball rolls down from the top of a grassy hill, reaches the bottom of the hill, continues to roll, and then starts to slow down and comes to a stop. What forces caused this ball's motion?

• Frictional force caused the ball to roll down the hill, but air resistance caused the ball to slow down and stop.

• Magnetic force caused the ball to roll down the hill, but gravity caused the ball to slow down and stop.

• The force of the hill caused the ball to roll down it, but gravity caused the ball to slow down and stop.

• Gravity caused the ball to roll down the hill, but frictional force caused the ball to slow down and stop.
