Force and Motion - applying your understanding

You are pushing a toy car on the floor. The car starts moving when you push it, but it slows down and stops after a while.

What happens when you push the car?

• When you push a car, you are pushing or pulling a car with elastic force which causes the car to stretch and return to its original shape.

• When you push the car, friction force is pushing back, and that is causing the car to move.

• When you push the car, you are applying force to it. This force makes the car start moving.

• When you push the car, you are stretching the car which creates tension force. The force makes the car start moving.

Why does the car eventually stop?

• When you push a car, you are making it change its shape, elastic force. After the car returns to its original shape, it stops moving.

• When the car is moving, friction force on the ground is pushing back, and makes the car stop.

• When you push the car, you are applying force to it, making the car stop.

• When you push the car, you are creating tension force. The force makes the car stop moving.

What forces are acting on the car?

• Applied Force and Friction Force.

• Applied Force and Tension Force.

• Friction Force and Elastic Force.

• Tension Force and Elastic Force.

You have a rubber band, and you stretch it by pulling at both ends. When you let go, the rubber band snaps back to its original shape.

How does the rubber band move when you stretch it?

• The force applied makes the rubber band jump forward, and then backwards.

• The force you apply causes the rubber band to move forward.

• You apply a force that causes the rubber band to stretch and change size permanently.

• You apply a force that causes the rubber band to stretch and change shape.

You have a rubber band, and you stretch it by pulling at both ends. When you let go, the rubber band snaps back to its original shape.

What do you think will happen if you stretch the band more?

• Nothing will happen. The force remains the same.

• The elastic force - the force that stretches and wants to go back to its original shape - becomes stronger.

• The applied force - the force of one thing moving another - becomes stronger.

• The friction force - the force of two things sliding against each other - becomes stronger.

How does the elastic force in the rubber band help it to return to its original shape?

• When you let go of the rubber band, the elastic force makes it snap back to its original shape.

• Tension force actually causes the rubber band to remain stretched permanently.

• Elastic force - the force of two objects sliding against each other - causes it to slow down and stop stretching.

• The rubber band doesn't actually stretch. Elastic Force just makes it seem that way.

Remembering:

What is applied force?

• A force that comes from pulling a string or rope connected to an object.

• A force that resists the motion of two objects rubbing against one another.

• The force caused by a spring being stretched or compressed, that wants to go back to its original shape.

• A force that is applied to an object by another object or person.

Remembering:

What is friction force?

• A force that comes from pulling a string or rope connected to an object.

• A force that resists the motion of two objects rubbing against one another.

• The force caused by a spring being stretched or compressed, that wants to go back to its original shape.

• A force that is applied to an object by another object or person.
