If an objects motion does not change the forces acting on it must be ___________.
Why might the amount of energy appear to decrease during a change?
When does a system store energy kinetically?
How many forces are acting on an object which is “resting” on a solid surface?
What is an energy resource?
What piece of equipment is used to measure mass?
Where should a force arrow start (or finish) on an object?
This question is on representing forces.
Draw an arrow representing the following forces. One box = One Newton.
Draw an arrow representing the following forces. One box = One Newton.
This question is on resultant forces.
Describe the resultant force acting on the following objects.
A cyclist being pushed forward by a force of 6N and pulled forwards by a force of 4N.
A Box being pushed forward by a force of 6N and pulled back by a force of 4N.
A Plane being pushed forward by a force of 4N and pushed back by a force of 12N.
This question is on how resultant forces effect the motion of objects.
A cyclist is moving forwards with an initial speed of 4 m/s. The bike is pushed forwards with a force of 10 N is and pushed backwards with a force of 4 N. Calculate the resultant force and describe how this will affect the motion of the cyclist.
A different cyclist is also moving forwards with an initial speed of 4 m/s. The bike is pushed forwards with a force of 4 N is and pushed backwards with a force of 4 N.
Calculate the resultant force and describe how this will affect the motion of the cyclist.
This question is about an investigation into forces.
A mass is pushed across a table by an elastic band. When it was pushed away by the elastic band it had an initial speed of 1 m/s. The speed of the mass slowed down until it stopped completely. Write an answer that: - Describes what force slows the mass down - Explains what causes the force - Explains what can be done to reduce its effect
This question is about energy transfers.
Describe the energy transfer and explain what causes the flowing changes.
Example) A battery powered motor is used to lift a car into the air. “The motor exerts a pulling force on the car.. Energy is transferred from the chemical store of the battery to the gravitational store of the mass."
A squashed spring pushes a ball so it starts rolling along the floor.
A train burns a fuel to pull a carriage until it starts moving.
This question is about analysing data.
A student worked out the amount of energy stored in 100g of different foods.
Use the information in the table to complete the bar graph.
Draw an arrow representing the following forces. One box = One Newton.
Draw an arrow representing a pushing force of 4 Newtons exerted on the back of the train.
